Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator provided with a freshness maintaining device for indirectly cooling a vegetable container arranged in a vegetable room from the surroundings so that vegetables and fruits can be stored for a long time.

[0002]

2. Description of the Related Art In recent years, refrigerators having a vegetable compartment that can be opened and closed by a drawer-type door have increased the concentration of ethylene gas released by the respiration of vegetables and fruits during the storage period of vegetables and fruits (hereinafter referred to as fruits and vegetables). In order to prevent the fruits and vegetables from spoiling, freshness maintaining devices that reduce the concentration of ethylene gas and maintain the freshness of the fruits and vegetables have been considered.

A conventional freshness maintaining device is disclosed in
Japanese Unexamined Patent Publication No. 238934/1990.

Hereinafter, a refrigerator provided with the above-mentioned conventional freshness maintaining device will be described with reference to the drawings.

FIG. 14 is a longitudinal sectional view of a conventional refrigerator.
FIG. 15 is an exploded perspective view of the vegetable container. 14, 1 is a refrigerator main body, 2 is a vegetable room, 3 is a drawer door, and has a frame 4 formed in a substantially U-shape by right and left frames and a rear frame. Reference numeral 5 denotes a vegetable container having an upper surface opening 6, and support flanges 7 are integrally formed at upper portions on both right and left sides, and are detachably mounted inside the frame 3. The drawer door 3 is attached to the front opening of the vegetable compartment 2 via the frame 4 so as to be openable and closable. 8 is a storage recess,
The vegetable container 5 is formed integrally with the space inside the container. Reference numeral 9 denotes a filter containing a catalyst for adsorbing and oxidatively decomposing ethylene gas and odor components. 10 is a vent hole 11
The freshness maintaining device 12 is formed by fitting and holding the filter 9 in the housing recess 8 so that the filter 9 does not fall off.

The freshness maintaining device 12 configured as described above
In the vegetable container 5, ethylene gas and odor components released by fruits and vegetables in the vegetable container 5 flow through the storage recess 8 through the vent hole 11 of the filter cover 10, touch the filter 9, adsorb and decompose on the catalyst in the filter, and It reduces the concentration of gas and maintains the freshness of fruits and vegetables.

[0007]

However, in the above-mentioned conventional construction, when the concentration of ethylene gas released from the fruits and vegetables in the vegetable container 5 becomes high, the ethylene gas is adsorbed by the catalyst built in the filter 9. In order to maintain the freshness of the fruits and vegetables by lowering the concentration, the concentration of eslen gas released from the fruits and vegetables is low in the low temperature zone in the vegetable container 5, and the disabling effect of the essence of eslen gas to promote the decay of the fruits and vegetables cannot be exerted. was there.

In order to prevent the filter 9 from falling off,
After being placed in the storage recess 8 of the vegetable container 5, it is covered with a filter cover 10 having a ventilation hole 11 and fitted and held in the storage recess 8.
The filter 9 is inconvenient for the user to remove and replace, and has a drawback that the filter 9 cannot be held if the filter 9 is damaged or lost at the time of replacement.

The filter 9 having a built-in catalyst has a filter cover 1 having a vent hole 11 on the front surface for preventing falling off.
Since the filter 9 is fitted and held at 0, the ethylene gas cannot be adsorbed because the ethylene gas cannot touch the catalyst built in the filter 9 when the ventilation hole 11 is closed with fruits and vegetables, bags or the like. There was a disability that could not be effective.

[0010] Another object of the present invention is to provide a freshness-maintaining effect that can keep fruit and vegetables fresh.

[0011]

SUMMARY OF THE INVENTION In order to achieve this object, the present invention provides a plurality of ventilation holes which incorporate an antibacterial freshness into which an aromatic substance having a freshening effect is incorporated into an antibacterial material having a volatile antibacterial component. The freshness-preserving antibacterial cassette is inserted from the upper portion into a storage portion integrally formed with holding plates protruding from both ends of the front opening opening at the upper portion and the front surface on the inner surface side of the vegetable container.

Thus, the antibacterial antimicrobial cassette can be easily attached and detached up and down with one touch.

[0013] Further, the ventilation hole of the fresh antibacterial cassette is provided on the back side of the storage portion of the vegetable container, and a certain gap is provided between the ventilation hole and the back wall of the storage portion. Also, a continuous rib is formed on the back wall and lower wall of the storage section from the upper opening end face to the lower wall front end face, and a ventilation path is provided. The fresh antibacterial substance contained in the fresh antibacterial cassette is a heavy volatile agent having a high specific gravity with a particularly high antibacterial antibacterial effect, and is provided at the top of the vegetable container.

As a result, the antibacterial and antibacterial effect can be further enhanced.

[0015]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention relates to a refrigerator main body, a vegetable compartment for storing vegetables and fruits, a vegetable container having an open upper surface which can be drawn back and forth into the vegetable compartment, and an antibacterial material having a volatile antibacterial component. A refreshing antibacterial cassette having a plurality of ventilation holes containing a refreshing antibacterial substance into which an aromatic substance having a freshening action is incorporated, a storage portion having an upper opening and a front opening on the inner surface side of the vegetable container, and both ends of a storage portion front portion And a holding plate protruding from the unit is integrally formed, and the fresh antibacterial antibacterial cassette is inserted from the upper opening and attached.

[0016] The volatile antibacterial antibacterial substance, which effectively controls the generation of ethylene gas released from the fruits and vegetables, is contained in the antibacterial antibacterial cassette. You can do it.

Further, a plurality of ventilation holes of the antibacterial antibacterial cassette are provided on the storage portion side of the vegetable container, and a certain gap is provided between the ventilation hole and the inner wall of the storage portion.

Thus, even when fruits and vegetables, bags and the like are placed on the front surface of the fresh antibacterial cassette on the inner side of the vegetable container, the ventilation hole of the fresh antibacterial cassette has a certain gap on the back wall side of the storage portion, so the hole is closed. Without releasing the antibacterial preservative component.

Further, a plurality of convex ribs continuous from the upper opening end face to the lower wall end face are formed on the inner wall and the lower wall of the storage portion of the vegetable container, and an air passage is provided.

With this, when the fresh antibacterial cassette is inserted, the fresh antibacterial cassette is pressed down by the plurality of ribs to form a cylindrical ventilation path. Even if it is placed, since the ventilation hole faces the ventilation path, the antibacterial freshening component can be smoothly diffused through the ventilation path to the whole vegetable container, and the freshening effect can be increased.

The antimicrobial material of the antimicrobial preservative contained in the antimicrobial preservative antibacterial cassette is a heavy volatile agent (for example, allyl isoquiocyanate, abbreviated as AIT) having a high specific gravity among the volatile antimicrobial components. It is provided on both sides of the vegetable container, or on the top of the front and back surfaces.

As a result, the volatile agent having a high specific gravity can be gradually released and diffused from the upper portion to the whole vegetable container, and furthermore, an efficient and highly effective freshening can be achieved.
